title: [Outcome beyond the 1st trimester of 305 pregnancies conceived by fertilization in vitro].
abstract: The obstetrical outcome of 305 pregnancies obtained by in vitro fertilization were reviewed: out of 275 pregnancies following fresh embryo transfers, 205 (74.5%) were single, 64 (23.3%) double and 6 (2.2%) triple). We observed increased frequencies of high blood pressure linked to older maternal age, bleeding in the late pregnancy and breech presentation, which could be associated to abnormal insertion of umbilical cord and/or placenta. Multiple pregnancies, especially the triple ones, are of the highest risk (intra-uterine growth retardation, low birth weight). Nevertheless the total fetal mortality remains low in our experience. Data about 22 pregnancies following cryopreserved embryo transfer, 5 after oocyte donation and 3 therapeutic abortions are also given.
